I previously had this,

fun Suite.mapsTo(expected: String) {
        val testObject by memoized<Any>()
        it("test value") {
            pp(testObject)
            outContent shouldRenderLike expected
        }
    }

    fun testObject(obj: Any?) {
        val testObject by memoized { obj }
    }
    
    describe("tiny object should") {
        context("render a single field") {
            testObject(TinyObject(1))
            mapsTo(
                """
                TinyObject(
                  int = 1
                )
                """
            )
        }
    }

but I find it very messy, and I can't use an infix....

[snowe]

this is the cleanest version I can get

fun Suite.validateTestOutput(testObject: Any?, expected: String) {
        it("test value") {
            pp(testObject)
            outContent shouldRenderLike expected
        }
    }

    describe("tiny object should") {
        infix fun Any.mapsTo(expected: String) {
            validateTestOutput(this, expected)
        }

        context("render a single field") {
            TinyObject(1) mapsTo """
                TinyObject(
                  int = 1
                )
                """

        }
    }

infix requires exactly two parameters. But you seem to need the Suite, the testObject and the expected

[snowe]

yeah I need a double infix. Any and Suite. if I had that then this would be easy.

X to Y mapsTo Z

Passing a Pair. You needn't use to, can make your own, you also needn't use Pair, any data class will do.

Hmm. nice idea. I was looking into writing a custom Spek class, following these directions (https://github.com/spekframework/spek/issues/115), but if I can’t get that to work then I’ll look into your suggestion. Biggest thing is that I still have to repeat the stuff every test class. I’d like to just have it in one location.
